Error in tournament on a given machine

[drvinceknight]

@marcharper and @meatballs not sure if you can offer any insight here, following #77 I'm giving the following code a go (a simple tournament with all strategies):

import axelrod as axl

from axelrod_fortran import Player
from axelrod_fortran.strategies import second_tournament_strategies

if __name__ == "__main__":
    players = [Player(name) for name in second_tournament_strategies]
    tournament = axl.Tournament(players, repetitions=1)
    results = tournament.play(processes=4)
    print(results.ranked_names)

I get the following error(s), then the tournament continues to run:

It does seem to hang on a final match (2015/2016):

Playing matches: 100%|█████████████████████████▉| 2015/2016 [02:00<00:00, 16.82it/s]

I get similar results when running different number of repetitions.

I seem unable to reproduce this on other machines of mine (where this code runs just fine).

I was aiming to give the full tournament a whirl for comparison with the reproducing paper and it could just be something weird on the specific server I tried so it's not the end of the world, I can run on something else.

Any immediate thoughts?

[marcharper]

Nothing immediate comes to mind. I can take a look at it later.

Only if you have time to spare. If it's not immediately familiar I suspect it's just something weird on the machine in question... 🙂

[meatballs]

File "/home/vince/.conda/envs/investigate-axlf/lib/python3.6/site-packages/axelrod_fortran/player.py", line 122, in _release_shared_library
shared_library_manager.release(self.original_name, self.index)
File "", line 2, in release

There is something very odd going on here. That last line should be referring to axelrod_fortran/shared_library_manager.py but it just says "string." The release method starts at line 98 in that file, so the line number is nonsense too, but the method name is fine!

[marcharper]

It doesn't reproduce on my machine and I don't see any good reason for the error. Perhaps the installation is in an unhappy state? I would try a new venv and see if you can reproduce it on the same machine or a similar one.

[drvinceknight]

Yeah I'm not too sure what's happening... I've reproduced it in a virtual env (on that same machine). Not sure what we can do as it doesn't reproduce on other machines...

Following #77 are the installation instructions for TourExec (https://github.com/Axelrod-Python/TourExec) any different? Perhaps I've not done that quite right on this machine...

If anyone would like me to try anything on this specific machine let me know otherwise perhaps we just close this issue (we can always reopen if anyone happens to stumble on this thing again)?

[marcharper]

No changes to installation instructions AFAIK, so I vote to close for now.
